DEVICE FOR WRINGING- WET LEATHER.

Application filed September 24, 1921. Serial No. 503,056.

To all whom t may Concern.'

Be it known that I, EDWIN F. HULBERT, a citizen of the United States,and resident of Milwaukee, in the county of Milwaukee and State ofIVisconsim'have invented a certain new and useful Improvement in Devicesfor IVI-inging l/Vet Leather, of which the following is a spe'cication.

The invention relates to a wringing wet leather.

Heretofore in wringing out wet leather it has been customary to use anapparatus in which half of the hide is wrung out during one operationand then the other half wrung out during another operation,necessitating a rehandling of the hide for a complete wringing. Theobject of the present invention is to'providea hide-wringing device inwhich vthe entire wringing operation is carried'V out without rehandlingthe hide.

A further object of the invention is to provide a hide-wringing deviceinwhich the hide is placed on a movable platen which is moved to,bringthe hide into contact with a wringing roller and then by tiltingsaid platen the hide is brought into Contact with another wringingroller to` accomplish the wringing operation.

The invention further consists in the several features hereinafter setforth and more particularly defined' by claims at the conclusion hereof.

In the drawings: Fig. 1 is aside view' of a device embodying theinvention; Fig. 2 is a front view thereof, parts being shown in section;Fig. 3 is a section taken on the line 3 3 of Fig. 2, with the platen inone of its wringing positions; Fig. 4 is a detail plan View of theplaten.

Iny the drawings the numeral 5 designates the frame of the machine, 6 apower pulley drivingly connected through a suitable clutch 7 with ashaft 8 carrying a gear 9 device for meshing with a gear 10 and a gear11 mesh-V ing with a gear 12. The gear 1() is mountedk on a shaft 13which carries a sprocket 14 connectedV by a chain 15 toa sprocket 16 'ona shaft 17.

The shaft 17 carries a gear 18 meshing with a gear 19 on ashaft 20.v Theshaft 17 carries a sprocket 21 connected by a chain 22 with a sprocket23Qo`nk the shaft v24 of a wringing roller 25. The shaf-t.20 carries asprocket 26y connected by Cha-in 27 with a sprocket 28 on the shaft 29of a wringing.

roller 30. As the shaft 20, due to the ,f ear-r ing connection 19, 18,revolves in the opposite direction to that of the shaft 17, the roller25 is rotated in the reverse direction to that of the'roller 30. Each ofthe shafts for the wringing rollers are mounted in bearing boXes 31yieldingly held in a lowerv position by means of springs 32.

A platen for the hide is formed bl side members 33 and shafts 34, 35 and36'. hafts 34' and 35 carry pressing rollers 37 and 38, respectively,and gears 39 and 40, respectively, at their ends while shaftv 36 formsal pivot about which the platen may tilt so as to bring either the gears39 into driven engagement with gears 41 on the shaft v2,4, or the gearsinto drivenengagement with gears 42 on the shaft 29. 'An endless apronor belt B passes over the rollers 37 and 38 and fornis a receiving anddischarge table for the hide H, as well as a' guide'for'it during thewringing opera-tion. The shaft 36 is journalled in slidable bearingblocks 43 mounted in inclined guides 44 so as to bring the platen' fromits'l lower hide-receiving position, shown in Fig. 1,I to its operativeposition, shown in Fig. 2, and for thisv purpose I use Sets of togglelinks 45 and 46 and connecting rods 47-operatively connected to thejoints of these links and to crank disks 48 mounted on a shaft 49 uponwhich the'gear 12 isvloosely mounted. The gear 12 is adapted to bedrivingly connected with the shaft 49' by means of a pin clutchincluding a pin 50 slidably mounted in a collar 51 keyed to the shaft 49and moved by aspiring 53 into locking engagement with either one of tworecesses 54 in the hub of the gear 12, said pin being automaticallywithdrawn from the gear 12 when' either one ofthe cams 55 on a rod 56are positioned in the groove 57 in the collar so as to engage ai groove58 in the pin 50 tok draw it out of engagement with the gear 12, whichaction' occurs after the shaft 49; hasl made about 1'00 half arevolution, as indicated in2 Fig. 3L The rod 56'isf normally urgedupwardly by means of a spring 58 and it is connected-'to anarin59 onshaft'60 operated by ay treadle 61. When the lower cam 55 isfinovedIkout 1'05 the pulley. On' a release/of the tilad'l the L10 upper cani 55is moved out of engagement with the pin 50 which engages the gear 'l2andthe platen is moved from the position shown in full lines in F ig. 3back to its lowered position, at which time the lower cam 55 diseiigagesthe pin 50 from the gear l2.

Then the platen is in its upper position it may be tilted in the mannerpreviously described so that one set of wi'inging rollers, such as 30and 38, and then the other set of wringing rollers 25 and 37 are driventhrough the gearing connections previously described. To eifect thistilting oi' the platen, .i provide cam shafts 62 at each end of themachine carrying cams 63 and 64 and I connect these up tor conjointoperation from either one ot two shai'ts 65 by means ot gears 66 and 67connecting each shaft 62 with theadjacent shaft 65 and by means ofsprockets 68 on said shafts connected by a chain 69, each of the shafts65 having a hand lever 70 for turning it which, through the gearingconnection just described, causes a rotation ol both of the shafts 65and the cam shafts 62. Then one of the levers 70 is turned in onedirection the cams 66 come into engagement with the members 33 of theplaten, causing its front end to tilt upwardly to bring the gears 4f()into mesh with the gears 4-2 and when one ot the levers 70 is turned inthe opposite direction-the cams 67 come into engagement with the members33 of the platen, causing its rear end to tilt upwardly to bring thegears 39 into mesh with the gears 41.

With this construction, when the platen is in its lower position thehide is placed thereon and on a depression of the treadle 61 the platenis raised to a wringing position. Then by tilting the platen to bringthe gears 40 and 42 into mesh while these gears are revolved through thedriving connection with the shaft 8, the lower half of the hide, asshown in Fig. 3, is wrung between the rollers 8G and 38 and as the upperrun or" the apron B moves toward the left. Then by tilting the platenVto bring the gears 39 and il into mesh the travel of the apron B isreversed and the other half of the hide is wrung between the rollers 35and 37. Thus the whole hide is wrung out and the platen then lowered forthe removal of the hide. rlhe wringing operation is thus quicklyaccomplished with minimum amount of handling of the l desire it to beunderstood that this invention is not to be limited to any specific formor arrangement oparts except in so far as such limitations are specifiedin the claims.

What I claim as my invention is:

1. ln a leather-wringing device, the cominsasoe bination of a pair otoppositely driven wringing rollers, a platen provided with rollers andan apron ruiming over said rollers and upon which the hide is placed,
